Heat Treatment

small and mid batches to meet your specific needs

Highest quality level is established by numerous technology processes developed and perfected by continuous industrial practice. Customer satisfaction is enhanced by series of services that can be selected based on special requirements to fully customize the heat treatment.

To develop tempered microstructure after hardening, the components are reheated to specific temperature bellow Ac1. Tempering temperature and time depend on type of steel and its geometry. Usually more than one tempering treatment is required to obtain desired properties.

Martensitic case-depth of up to 3.0 mm is developed by increasing surface carbon content in austenitic region with high carbon solubility. Subsequent hardening and tempering are performed to reach desired properties.

For part dimension up to 600 x 600 x 900 mm and weight of up to 500 kg.

Case with improved hardenability and temper resistance due to nitrogen addition.

Technical specification

Treatment is usually carried out in a temperature range from 850 to 890°C in carbon and nitrogen rich atmosphere to develop martensitic case-depth of up to 1.0 mm. Subsequent hardening and tempering are performed to reach desired properties.

For part dimension up to 600 x 600 x 900 mm and weight of up to 500 kg.

Components after being subjected to plastic deformation: gross machining, welding, cold forming, forging or hardening, and generally components where tight dimensional tolerances are required. Generally for steels in annealed or hardened and tempered condition.

Benefits

Reduced residual stresses in bigger and complex parts.

Treatment has no substantial effect on steel microstructure.

Dimensional stability achieved with lowest distortion.

Technical specification

Components are heated below the eutectoid temperature (Ac1) between 450 - 650 °C, using a particular heating and cooling regime. Temperatures are similar to the process called tempering.

Components after machining, welding, cold forming, forging, or generally after plastic deformation, to relieve residual stresses and obtain homogeneous and fine-grain structure. Normalization is primarily used on carbon and low-alloyed steels
